As a structural engineer, I see a good opportunity to make reinforced concrete design software available in a SaaS format. The competition is outdated, clunky, requires local installation and messing about with licenses. Design firms are paying $1000-$3000/year per user/seat for what amounts to a pretty basic app.
Unfortunately, there are very few people that understand both computer science and structural engineering.
